When groups of yarns are interlaced and a braid is being formed, the center of the braided structure represents the point of braiding. That’s where the interlacement occurs and the structure becomes visible. The point of braiding is clearly visible when braids are constructed on round devices or handheld, where layers of interlaced yarns are built one on top of the other. The point of braiding is less visible when braids are constructed upwards such as on a maypole or flat.
The point of braiding (called Kensaki in Japan) provides a great deal of information to the braider: it can tell whether the completed sequence of interlacements has been executed correctly, and whether the tension (determined by the visible length of the stitches) is correct.
When the point of braiding is not visible, other visual cues must be used to determine whether the sequence of interlacements was executed correctly — such the exterior appearance of the braid.
